1st, let's calculate the side AB = c in applying the law of cosine:

AC² = BC²+AC² - 2AB.BC. cos87°)
c²= 10.1²+9.8²-2(10.1)(9.8)(cos(87)
c²=102.01 + 96.04 -196.96cos(87) 
c² = 187.74 and c = 13.7
Having calculated the 3rd side, now we can apply Heron's formula for the area:
AREA = √p(p-a)(p-b)(p-c), where p is half the perimeter or p=(a+b+c)/2 =16.8

AREA = √16.8(16.8-10.1)(16.8-9.8)(16.8-13.7)
AREA = 49.42 OR 49.4 unit²

1. Which of the following describes a demand schedule?
NikAS [45]

1)d. The quantity of a product that consumers are willing and able to buy at each unit price

2)C. The product has a lower price

3)c. The quantity demanded for chips will decrease and the demand for salsa will decrease.

4)I didn't understand your question about this one but I can explain the graph:-)

according to this diagram

the supply curve has shifted backward i.e supply is decreased so, with the decrease in supply the price of good increases and as a result of increased price the quantity demanded decreased.

5)B. Average consumer income has decreased, with Good A being an inferior good. ( because as you can see in the diagram that demand for good A is increased)

demand for inferior goods increases with the decrease in income. For example: if your income decreases you'll start travelling from bus instead of train.

6)B. Stacy wanted ice cream a bit more than a cupcake but chose the cupcake when the price of ice cream increased.

Assume the economy is currently in long-run equilibrium. An increase in the money supply will affect unemployment in the short r
forsale [732]

A money supply go up and be inflationary in nature if the unemployment rate is below the natural rate and thus there will be high rate of unemployment.

<h3>What does it implies when the economy is in long run equilibrium?</h3>

An economy that is to be in long-run equilibrium will have the real unemployment rate to be equal to that of natural rate of unemployment.

Note that a boast in the money supply will influence unemployment based on the fact that unemployment rate is bigger than the natural rate of unemployment, and thus the rate of inflation is said to be going done.

When the level of output is higher than  employment output, an unemployment rate tends to increase and thus pressure is placed on  increased wages and prices.

Conclusively, Note that Lower unemployment rate will lead to lower presence of workers in the companies .
